Abstract
The utility model discloses a valve with a split valve body structure. The valve comprises a valve body, a valve core and a valve rod, wherein the valve rod and the valve core are connected; a positioning shaft which is coaxial with the valve rod is arranged at the lower part of the valve core. The valve is characterized in that the valve body is provided with a left valve body and a right valve body which are symmetric with each other; a groove is formed in the left valve body; when the left and right valve bodies are combined, the groove becomes a positioning hole and the positioning shaft is arranged in the positioning hole. According to the valve with the split valve body structure, for the valve core with the positioning shaft, convenience is brought for assembly work, the assembly time is shortened and the assembly efficiency is improved.
Description
Technical field
The utility model relates to a kind of valve.
Background technique
The structure of valve is generally made up of valve body, spool and valve rod, and wherein spool and valve rod are connected as a single entity, and for general valve, its spool top connects after valve rod, and its underpart is smooth circular-arc (without rear axle spool location).Therefore, also just different in the structure of valve body.The valve of said structure, as long as open a suitable breach on valve body, can be placed on spool in valve body.And for thering is positioning axis structure on spool, because its positioning shaft and valve rod are in coaxially, adopt an above-mentioned suitable breach, spool cannot be placed in valve body completely.And very short in valve core lining fluorine working life, therefore, need to improve the structure of valve body and spool.
Summary of the invention
In view of the problem that background technique exists, the technical problems to be solved in the utility model is to provide a kind of split type valve body that can assemble valve fast and the valve of valve core structure.
For this reason, the utility model adopts following technological scheme to realize: a kind of valve of split type valve body structure, comprise valve body, spool, valve rod, described valve rod and spool are connected to monolithic construction, the bottom of described spool has the positioning shaft coaxial with described valve rod, it is characterized in that described valve body has left valve barrel and right valve barrel, on described left valve barrel, there is groove, described left valve barrel and right valve barrel are symmetrical, after the valve body zoarium of described left and right, groove on it forms positioning hole, and described positioning shaft is placed in described positioning hole.
In the valve body of described left and right, be provided with the valve seat mating with described spool, described valve base inner wall is provided with lining fluorine layer.
This structure of the present utility model, as long as the spool with positioning shaft is first placed on left valve barrel or right valve barrel, then closes second half valve body to be fixed, just can easily spool be placed in valve body completely, assemble quick and conveniently, the installation time of shortening, has improved efficiency of assembling.
Brief description of the drawings
Further describe by reference to the accompanying drawings again details of the present utility model below.
Fig. 1 is the utility model embodiment one STRUCTURE DECOMPOSITION figure;
Fig. 2 is the utility model embodiment one plane structure chart;
Fig. 3 is the utility model embodiment two STRUCTURE DECOMPOSITION figure.
Embodiment
Embodiment one, with reference to Fig. 1, Fig. 2, the valve of this split type valve body structure, comprise valve body, spool 4, valve rod 1, described valve rod 1 is connected with spool 4, described spool 4 is " O " type spool, the bottom of described spool 4 has the positioning shaft 6 coaxial with described valve rod 1, described valve rod 1 and positioning shaft 6 form overall structure with spool 4, described valve body has left valve barrel 7 and right valve barrel 5, on described left valve barrel 7, there is groove 9, described left valve barrel 7 is symmetrical with right valve barrel 5, described left and right valve body 7, after 5 zoariums, groove 9 on it forms positioning hole, described positioning shaft 6 is placed in described positioning hole, described left and right valve body 7, in 5, be provided with the valve seat 8 mating with described spool 4, described valve seat 8 inwalls are provided with lining fluorine layer.In the time of assembling, first the spool 4 with positioning shaft 6 and valve rod 1 is mated with left valve barrel 7, then right valve barrel 5 is closed, by bolton, finally in the through hole of valve rod 1 and valve body, insert stuffing box packing 3, compress with gland 2, its assembling is quick and convenient, has improved greatly the efficiency of assembling of valve.
Embodiment two, with reference to Fig. 3, the spool of the present embodiment is " V " type spool, other structure is identical with embodiment one, does not repeat them here.
Claims (2)
1. the valve of a split type valve body structure, comprise valve body, spool, valve rod, described valve rod is connected with spool, the bottom of described spool has the positioning shaft coaxial with described valve rod, it is characterized in that described valve body has left valve barrel and right valve barrel, has groove on described left valve barrel, described left valve barrel and right valve barrel are symmetrical, after the valve body zoarium of described left and right, the groove on it forms positioning hole, and described positioning shaft is placed in described positioning hole.
